The Schedule referred to-in these Letters'Patent and making part of thi name.

To all whom tt may concern:

Be it known that I, JOSHUAv E. AMBRosE,'-of Lombard, Du Page county, Illinois, have invented, made, and applied to use, certain Improvements in the Gonstruction of Lanterns, and do hereby declare that the following is a full,-clear,. and correct description of the same, reference being had to the accompanying draw ings, making part of this specification, and to the let" ters of' reference marked thereon, in which- Figure lis a vertical out section of my improved lantern. I

Figure 2 is a side elevation of the same.

Figure 3 is a view of the top detached from the lantern. i

In the drawings, like parts of the invention are pointed out by the same letters of reference.

The nature of the present*inventionV consists- (11,) in providingv the globe A with a dome, as/more fully vhereinafter set forth.

(b,) in combining witha globe so constructed, a reflecting or deflectingl surface, as more fully hereinafter set forth.

(0,) in the use or employment of mica in connection with the band.

The object of the present invention is the production of a lantern,'wbich, from the fact that the light can be reflected and thus utilized, will be found superior, for many purposes, to lanterns, as ordinarily constructed.

To enable those skilled in the arts to make and use my invention, the following description will be-found sufficient. A

A shows the globe of the lantern, which, instead vof being made as the ordinary lanternsglobe is, has the glass continued in its manufacture, so as to form a r dome over and above the globe proper.

,. This globe A is covered or backed with some white metallic or any good retlecting-substance, B, which is intended to prevent the light from passing through the glass, and to throw the same downward, and will be found at the same time to materially protect the dome-portion of the globe from damage by breakage, the metal used being passed over and beyond the glass.

C shows the top, formed of metal and mountedupon the upper portion of the globe A, to which is attached the wire ringer handle D.

This top O has upon its interior a wind-breaker,

l formed by bending up angular-ly the metal, whichotherwise would constitute a flat surface, the metal having' been cut into the desired form to expedite such bending. l

Theturned-up portions of the metal serve to check, in a great measure, the entrance of currents of cold air intothe lantern.

The top is surmounted bya cap, F, consisting of a concaveV plate of metal supported upon the supports f, attached to the top of the lantern, which cap is placed sufficiently above the top to leave an open space betweenthe top and the cap, and allow the air to -pass fount, which ring has its portion directly'below the oilpot.or fount out away to allow the deflected light to pass through the glass bottom of the oil-pot or fount, and is also perforated to admitV air to the flame.

Upon the raised portions of this ring J' arerplaced loops of wire, and at a short distance below these loops are placedwiresprings, the ring J being slotted upon its -rai'sed portion, to allow pinslsecured upon the interior of the band G, to enter into the same.

After the pins have entered these slots, the ring J may be turned, by which the pins will be brought and held between the loops and\the springs, thus retaining the oil-fount .within the lower portion of the lantern. Such being the construction, the lantern maybe used as lanterns are ordinarily used.

The great object attained in the use of v a lantern, v

constructed as just described, is that from the peculiar formation given to the globe, and the abilityvr to back the same .with some proper substance, the light will be deected or reflected, and thus enable the lantern to be used Iformany purposes for which lanterns are-not usually employed, While the light beingdeflected, will be found much more agreeable, and not injurious to the sight..l

Again, by the vinsertion of the mica, or like mate-N rial, in the band, and by perforating the flange of the lantern, and cutting away. a portion of the ring J, the deflected light can be thrown below the lantern.

'lhe dome-shape given to the" globe, allows the air entering at the top of the lantern (which'air is met by the heated air rising from the lamp) to be spread over.

this dome-surface, thus 'not obstructing the draught, while the glass formsa certain protection for the metal employed, preventing the same from being 'tarnished by the hea't, and the metal, in turn, prote cts the glass.

The wind-breaker, placed within the top, as shown, serves to prevent the currents' of cold air from entering the lantern .or globe too rapidly.

In some cases, the glass globe can be used without the metal boeking, in which case the glass forming the as described, a deeoting-surfafce, for the purposes set globe can be corrugated or. frosted upon its exterior, forth. so as to render it less liable to be broken, and at the 3. The combination, with the band G, ofthe plates sume time increasing its deecting-power. of mice, or some equivalent material, as and for the Having thus set forth my invention, purposes described. 'W'liat I claim us new, is- JOSHUA E. AMBROSE.
